To all whom may concern: 7

Be it known that l, Harem D. Unseen, a citizen of the United States, andresident of Detroit, WVayne county, State of Michi-- gan, have inventedcertain new and useful improvements in Motor-Vehicles, of which thefollowing is a specification.

This invention relates to motor vehicles andparticularly to the drivingand braking mechanism thereof.

@ne of the objects of this invention is to provide an improved mountingfor the transmission mechanism casing of a motor vehicle.

Another object is to provide a casing for the transmission mechanismwhich may be flexibly mounted on the vehicle.

Another object is to provide in a transmission casing, an improved meansof supporting the antidiriction bearings therein. Another object istoprovide in a transmission casing, a supportingmember for theanti-friction hearings thereln, which support may be also used as ameans otfleaihly mounting the casing on the vehicle.-

Another object is to provide a transmission casing which may be rigidlysupported at two points, and rotatahly or flexibly mounted at a thirdpoint on the frame of the vehicle.

Another object of this invention is to provide an improved means outmounting the brake mechanism and transmission casing on the frame o f;the vehicle.

Another object is tov provide an improved form of transmission brakemechanism which may he so secured to the frame of the vehicle adjacentthe transmission mechanism casing, that the braking strains of thenonrotating bralre elements are not transmitted to the said casing.

Another ohject is to provide a brake mechanism comprisin a .hrake drummounted on a propel er shaft which is mounted in the transmissionmechanism cas ing, and provide a support for the non-rotating brakingelements which co'tiperatte with the braking drum, the support orbracket also supporting the transmission casing on the frame in such amanner that the braking strains of the hraking elements are nottransferred to the transmlssion-cas- Another oh ect is to prov1de animproved means of adyustmg the bralnng elements specification of LettersFatent.

and braking shoes relative to the braking drum.

Other objects will appear from the following description taken inconnection with the accompanying drawings which form part of thisspecification and in which z- Figure l is a plan view of a portion of amotor vehicle embodying a form of the transmission casing and brakemechanism which are the suhjects matter of this application;

Fig. 2' is a rear elevation of the parts shown in Fig, 1, showing partsbroken away;

Fig. 3 is a longitudinal vertical section approximately on the line 3--3of 1;

Fig. 4 is a longitudinal vertical section approximately on the line H ofFig. 5, having some parts broken away and some in elevation to moreclearly show the adjusting' feature;

Fig. 5 is a transverse vertical section approximately on the line 5-5 ofFig. i; and

Fig. 6 is a detail view of a form of sup porting member for thetransmission casing and bearing therein.

Referring to the drawings, the frame 10 comprises side members 11 andtransverse members 12 and 13. A casing 14 tor-the transmission or speedchange mechanism is shown as having lugs 15 through which the casing maybe secured as by bolts 16 at two points on the frame. 7

Referring particularly to Fig. 3, a driving or propeller shaft 17 isshown asiro tatably mounted in anti-friction bearings 18 which aremounted in a supporting member 19. lhis supportin member may badetachahly secured to t e casing it as by bolts and nuts 20, and flexiblyor rotatably mounted in the opening 21 of the bracket or supportingmember 22 which may be secured as by rivets 23 to thetransverse framememher. 13.

'lhecasing 14: is adapted to carry oil'for the pro er lubrication of therotating elements t erein, and to prevent the leakage of oil therefrom.an oil retaining ring having packing 25 arran 'ed therein adjacent theshaft 17, is suita ly secured as by holts26 to the supporting member 19.

lhe bracket 22 is shown as having an up wardly extending portion 27having a boss 28 arranged thereon and havin a downwardly extendingportion 29 having a split lltl boss 30 formed integral therewith.Suitably secured in the boss 28 as by nut 31, is a trunnioned or fixedpivot 32 having brake arms or elements 33 and 3d suitably journaledthereon adjacent one of their respec" tive ends, thearms being held onsaid fixed pivot 32 as by the shoulder 35 shown as formed integral-withsaid pivot.

At 36 are brake shoes having ears 37 formed thereon intermediate theirrespective ends and adapted to be pivotally mounted on the brakeelements 33 and 34, respectively. These brake elements and theirrespective shoes 36 are adapted to be brought in contact, in a mannermore fully hereinafter described, with the brake drum 38, which issuitably secured to the propeller shaft 17 as by nuts 39.

Pivotally secured to the lower end of the brake arm 33 is an actuatinglever 40 adapted to be swung about the pivot 41 for oper ating theconnecting link 42 which is pivotally secured theretoat one end as at43,

and is also pivotally secured at its opposite end to the lower portionof the brake arm 34: as at 4%. It will be seen that the distance betweenpivots 43 and d4: may be varied by means of the wing nut 45, whichsecures said link to the lower portion of the arm 3 I I llt will be seenthat arranged on the link 42 is a stop &6 which is limited in itsmovement in one direction by means of the adjustable abutment 47 whichis threaded in the boss 30 and locked by means of the wing nut 48.Surrounding the link 42 and extending between the lower end of the arm34; and said abutment a7, is a retracting means in the form of thespring 49, the

tension of whichmay be varied by means of the adjustable abutment l7 andthe wing nut 45. v I

From the above description it will be seen that when the brake operatingrod 50 is moved forwardly in any well known manner, the bell crank 51will raise the arm of the actuating lever ddupwardly by means of the'link 51, bringing the brake arms 33 and 34 into contact with the brakedrum 38 and. upon release of the rod 50 the spring 49 will be caused bythe adjustable abutment 47 to move the arm 34% away from the brake drumuntil the stop. 4&6 is limited in its movement also by the abutment 47,and

then a further releasing movement of the rod 50 is caused by a secondretracting spring 50 to retract the brake arm 33 from the drum. .Thus itwill be seen that means are provided which cooperatewith the abutment 47to disengage both of the brake arms.

--And in order to assure a perfect contact between thebrake shoes 36 andthe drum 38, there are formed in the arms 33' and 34, respectively,bosses 52, in which are adjustably secured bolts 53,, which coiiperatewith the adjustable abutment 4:7 to center the shoes relative to thedrum and thus the shoes may at all times be keptconcentric with thebrake drum. I I

It will also be seen from the above de scription that by means of themounting provided for the brake elements and the transmission casing,the braking strains of the arms 33 and 3a are transmitted directly t6the transverse member 13 preventing any torsional strains from the brakeshoes from being transferred to the transmission casing 14:, which isrotatably mounted in the bracket 22;
